First of all, I want to say I'm a big fan, I can't stop playing. I don't know anything about the Valve Source engine, and I was wondering if it would be possible to recreate the single player missions, and if so, are there any plans to do so? Because I would definately be all over that.
Edit: I guess it would have been smart to search older posts before creating a new one. My bad. Anyways, I'll be quietly hoping and waiting for single player while I enjoy this awesome multiplayer action.
